Multi-axis polishing machine of back cover of smart phone

Abstract

The invention discloses a multi-axis polishing machine of a back cover of a smart phone. The multi-axis polishing machine of the back cover of the smart phone comprises a machine cabinet. The two endsof the machine cabinet are provided with a feeding conveyer belt and a discharging conveyer belt correspondingly. Clamp devices are arranged between the feeding conveyer belt and the discharging conveyer belt. Automatic polishing devices are correspondingly arranged in front of the clamp device. Each automatic polishing device comprises a longitudinal lead screw mechanism fixed to the tabletop ofthe machine cabinet, wherein the longitudinal lead screw mechanism is provided with a U-shaped sliding frame, a swinging frame is provided with a U-shaped rotating frame, the front face of the U-shaped rotating frame is provided with a polisher, the back face of the polisher is meshed with a gear through a rack, the gear is connected with a rack motor, the rack motor is fixed to the back face ofthe U-shaped rotating frame, an end shaft of one end of the U-shaped rotating frame is connected with a rotating motor through a belt transmission mechanism, an end shaft of the other end of the U-shaped rotating frame is provided with a baffle, and the rotating motor is arranged on the U-shaped sliding frame, and the end face of the U-shaped sliding frame is provided with a laser sensor used forsensing the position of the baffle. The multi-axis polishing machine of the back cover of the smart phone can achieve automatic polishing of the arc line edge of the back cover of the smart phone, ishigh in polishing efficiency and achieves flexible control.

Description

technical field [0001] The invention relates to the technical field of mobile phone processing equipment, in particular to a multi-axis grinding machine for the back cover of a smart phone. Background technique [0002] A large part of the shape and appearance of the smartphone is reflected by the back cover of the smartphone. The back cover of the smartphone is generally processed by injection molding. For bumps or pits, in order to improve the smoothness of the surface, the more common method is to grind them with bare hands by workers. The metal chips generated during manual grinding float in the air, which can easily cause serious damage to the human respiratory system, especially the lungs. Injury, affecting people's health; and the accuracy of manual grinding is low, often the friction area is large at one time, generating a lot of heat, resulting in slight deformation of the back cover of the mobile phone, affecting the product quality of the back cover of the smartph...

[0002] A large part of the shape and appearance of the smartphone is reflected by the back cover of the smartphone. The back cover of the smartphone is generally processed by injection molding. For bumps or pits, in order to improve the smoothness of the surface, the more common method is to grind them with bare hands by workers. The metal chips generated during manual grinding float in the air, which can easily cause serious damage to the human respiratory system, especially the lungs. Injury, affecting people's health; and the accuracy of manual grinding is low, often the friction area is large at one time, generating a lot of heat, resulting in slight deformation of the back cover of the mobile phone, affecting the product quality of the back cover of the smartphone, and the efficiency of manual grinding is low. ; Although there are also grinding wheels used to polish the back cover of the mobile phone, because the position of the back cover product of the mobile phone is fixed in the fixture and cannot rotate freely, the grinding wheel cannot realize the grinding of each edge and each edge, and the surface deformation of the back cover of the mobile phone is seriously deformed after grinding , especially for the curved edge of the back cover of the mobile phone, it is mainly processed by manual grinding by experienced workers
